Thanks.
I'm not sure increasing warmth is something I am necessarily after. I am probably more interested in clarity, detail and neutrality.
To be sure, Mills resistors are the ones I've been familiar with for years, and I most recently used them in a pair of satellite speakers. But I am curious to know how the others compare. From what I can find, the Mundorf M-Resist Supremes are "brighter". The Jantzen Superes Resistors are thought to be clear and neutral, as well as exceptional value. The problem with choice of all these different resistors, is having sufficient information to make an informed choice -- especially when it is difficult for people to audition each one. So if there are those of you who have compared or have some perspective on this, it would be great to see if some kind of consensus emerges.
I assume, and please correct me if this is incorrect, is that the differences in resistors (particularly those of the same type) would be less less audible in bass low-pass circuits that in tweeter circuits. Perhaps in my tweeter circuit I should just open my wallet and put in Path resistors - which I suspect would be wasted in the bass low-pass board.
Finally, in this era of crazy tariffs and trade wars, I wonder if ordering from Parts Connexion in Canada would be a problem.
